WELT ATTACHMENT FOB KNITTING-MACHINES. I

Specification of Letters Patent. PatentedfA 12, 1 92 1 Application filedFebruary 18, 1919. Serial No. 277,847.

I is a specification.

The principal object of the present invention is to provide atransferrer, which is ameans for taking stitches ofl'the needles bytheir wale loops, and subsequently putting the wale loops onto theneedles in the manufacture. of welts on'stockings and the like, andwhich shall provide ample space for the passage of a needle even if theparts are slightly out of time, and which can be readily made and isstrong and reliable in action.

The invention will be claimed at the end hereof but will be firstdescribed in connection with the embodiment of it chosen forillustration in the accompanying drawings forming part hereof and inwhich'-,

Figures 1 and 2, are top or plan views illustrating parts of a weltattachment equipped with transferrers embodying features of theinvention and showing the same in different positions.

Fig. 3, is a vertical section of the same, and r Fig. 4, is a top orplan view of one of the parts'of a transferrer.

In the drawings 1, is a dial or carrier arranged centrally of the circleof needles 2,

- and provided with grooves 3, formed between ribs 4. member provided atone end with a hook 6,

I and having its shank 7 olf-set to one side of the plane of the hook.Each transferrer consists of two of these parts 5, arranged with theirhooks face to face and with their shanks inadjoining grooves 3, so thatparts of adjacent transferrers are disposed 1n ad joining grooves.

5, is a transferrer part or The transferrers are projected as shown inFlg. 1, and retracted as shown in Fig. 2, by means of well understoodmechanism,

not shown, which may operate upon butts 8, pro ectlng from thetransferrers, and the dial 1, is subjected to slight turning-movement toline the transferrers ,with either the needles 2, or the spaces betweenthem. When the transferrers are alined with the spaces between theneedles the transferrers are projected and retracted and their hookstake wale loops and hold them while the material for the welt is made.Then the dial is turned to aline the transferrers with the needles andwhen the transferrers are ,proj ected the needles work through them andtake the loops from them. Here one advantage of this invention may beemphasized and it is that the space between the parts of thetransferrers extends all the way to the dial so that there is no dangerof the needles striking the transferrers even if the movement of theparts be out of time. When the transferrers are retracted -the needlespass between the parts at the hook portions thereof. .Evidentlythe partsof the transferrers are easily manufactured and assembled in thegrooves, and when assembled, the transferrers are strong and reliable.

What I claim is:

A welt attachment for knitting machines comprising the combination of agrooved dial or carrier, and transferrers each consisting of two partswhereof each is provided with a hookand with an oif-setshank,

and the hooks of each of the parts of a trans- EMIL J. FRANCK. J
